When a "9-point" tax is mentioned, it usually refers to a 9% tax rate. When we say that a ** contains 9 points of tax, it means that this ** already contains 9% of the tax amount. Then, when we want to claim the tax amount in this tax included**, or deduct the tax amount from the tax included**, we need to calculate it accordingly.
First of all, we want to make it clear that when calculating the tax amount or deducting the tax amount, we should calculate it based on the ** excluding tax. This is because taxes are usually calculated based on excluding taxes and then added to them. So, if you have a tax** and want to claim the amount of tax in it, you need to divide the tax** by 1 plus the tax rate (expressed as a decimal), which is 109 (corresponding to a 9% tax rate)
For example, if the tax included** of an item is 100 yuan, and the tax rate is 9%, then the tax amount in this ** is calculated as: 100 109 = 91.74 yuan, that's excluding tax**. Then, multiply the tax exclude by the tax rate ** to get the tax amount: 9174 × 0.09 = 8.26 yuan. Therefore, the tax amount in 100 yuan including tax** is 826 yuan.
Conversely, if you want to deduct the tax amount from the tax included**, you need to multiply the tax included** by 1 divided by 1 plus the tax rate (again expressed as a decimal, i.e. 0.).9174）。Continuing with the example above, if you want to deduct the tax amount from the $100 tax included**, the calculation is: 100 09174 =91.74 yuan. That's excluding tax**. Then, multiply the tax exclude** by the tax rate to get the amount of tax that should be deducted: 9174 × 0.09 = 8.26 yuan. Therefore, the ** after deduction should be 9174 - 8.26 = 91.74 yuan.
To sum up, for a 9% tax rate, tax included** divided by 109 to get tax exclude**, multiplied by 092 after receiving the tax deduction**. In turn, excluding tax** multiplied by 109 gets tax included**, divided by 092 gets the amount of tax.
In practice, we have to make these calculations accurately to ensure that we get the correct amount of tax or tax**. If we don't do accurate calculations, it may result in inaccurate cost calculations or problems with our tax returns. So, whether in a business transaction or in the tax filing process, we should be clear about how to correctly calculate the tax at 9 points.
